Mega RX-7 "Roadster" build (pics)

Well, It's time for the "official" thread regarding my car's most recent project. Goals are:

Major weight reduction, Full race prep(cage, gutting, etc)
Miata IRS
FC front suspension w/R&P PS conversion
Right hand drive swap
Wide Body kit
Removed roof and back hatch (Roadster)
Fiberglass body pannels (doors, hood, fenders,etc)
Full engine rebuild (yes, it's a V8......)

Sounds fun huh? Here are some pictures of the tear down so far. I need to take some more but this is what the car looked like last week.










I'll keep the progress updated here, but you can also follow the cardomain site here : http://www.cardomain.com/id/drivergt5

All sounds cool except one thing. Too bad you had to put 8 pissed-ons in the car. Shame...

It woulda been much cooler with a PP 12A or 13B.

a pp 12a or 13b would have even less low end torque, the V8 is a good engine. If it makes the car go fast... then its good in my book, at least he's not putting a 4 banger in it.... which engine is going in? I was thinking of a 351 windsor, since my 12 a, doesnt like to run in the rain anymore

One of the Drag guys is at about 1500HP on a No "NOS" motor.

Jesus Padilla runs I think high 8's low 9's from 1.3L, N/A, No Juice. All motor. That's with what, 87 CI? Compared to 500+ CI. You can't compare. Let me see any V-8 do that. Only thing I know that is way more sick, but'll never fit in a car is a 12 cyl diesel that runs 708,000 hp, and 3,000,000 lb/ft. of torque....at 108 rpm. It's a cargo ship engine.

ok... here is the way i see it..... hp/CI isnt worth anything if you believe that it is, go buy a honda S2000..... HP/MPG and HP/weight is much better...... i honestly think that the rotary engine is awsome, if mazda engineers sat down and worked hard on it, they could make an engine which could rock the world..... but, 1.3 letres with a 20mpg fuel efficiancy is not that good.... i can spend the same amount on gas, and have 100 extra hp on tap if i switch to a V8..... and if i turbocharge my 12a, my mpg goes down so to be honest... whats the point!
plus.... parts for a V8 are a dime a dozen, a rebuid kit is like $500..... but a rebuld kit for a rotary is upwards of $1500...... I like to spend less and go faster than the honda boys... this seems like a good way

You're absolutely right. But why be like everyone else? That's why we have rotary's. I don't wanna be a I4 guy. I dare to be different, and as little as I have in my car, i can run close to 14's, and still get 20 mpg. RB SP Exhaust, Holley intake kit, Holley Blue fuel pump, and pressure regulator. Mild SP.

1500 for car, exhaust came with it, the motor was 900, and came with the intake/carb. Pump was $50 on ebay. I can't complain.

thats my biggest problem.... I want my stuff to be unique, but i dont like spending loads of money.... so im stuck between the street port primaries, periferal port secondaries idea, and giving in to the V8..... i still havent decided yet
regardless, this car that '85 GSL 302 is building should be a wickedly fast car! I cant wait to see what a roadster with a wide body looks like, i cant even begin to imagine it!

sounds sweet, i just don't understand why you're gonna use a miata rear end with all that torque? the rear will be nice suspension wise, but will it take the abuse your v8 is gonna give it?
